New Publication

Matts project on tertiary amine organocatalysis is published in ACS Sustainable Chemistry and Engineering special issue on Mechanochemistry. Matt has demonstrated in some cases that the aza-MBH reaction can be run in significantly shorter reaction times (3 hours compared to 3 days) in the absence of reaction solvent. Matt also observed that asymmetric induction is possible in the absence of solvent although seemingly diminished in comparison to having solvent present, as ever, a privilege to work with Louis Morrill on this.

Welcome to Dr Jamie Leitch

The group welcomes Dr Jamie Leitch as PDRA, working on a Leverhulme Trust funded project in collaboration with Prof. Adrian Porch and Dr Rebecca Melen . Jamies project will explore the use of Microwave analysis to determine the frustratedness of Lewis Pairings. Jamie was previously PDRA in the Dixon group and PhD with Prof. Chris Frost

PhD Student gives a talk at GSK Postgraduate Symposium

We're proud to have Will Nicholson representing the group today with a research talk at GSK's online Postgraduate Symposium event! Will will talk about mechanochemical C-N bond forming reactions, we expect many questions about pros and cons of milling - hopefully stimulating for all!

New Publication

Andy, Will and Harry's thiol arylation project is published in Organic Letters. This took significant effort from Andy to increase the substrates scope using zinc metal. Andy found that addition of zinc metal to the reaction minimised disulfide formation and opened up the substrate scope to permit inclusion of alkylthiols. This project also highlights the robustness of reactions when conducted under ball-milling conditions

Congratulations to Dr Stark

Congratulations to Roddy who passed his viva today and is the third member of the group to pass with a PhD (this time collaboratively with Ian Fallis), we are very proud of his achievements, getting up for those early morning preparations of Radio-FDG for patients must have been very rewarding....especially during the afternoon problem sets!. Thanks to Matt Tredwell and James Hodgkinson for examining via Zoom, its a shame we could celebate in person, but we still sent a tankard (and drinks). The tankard reads 'llongyfarchiadau'! Good luck Roddy.

Collaborative publication accepted! This was an interesting project comparing the thermal stability of dizonium salts with thier triazene congeners explored with the Harris Group. Congratulations to Christiane, Samy, Low and Colan, who collaboratively syntheised these molecules in batch and flow and performed the analysis
